JOHN H. OSBORNE, OF ANDERSON, INDIANA.

THlLL-COUPLING.

SPECIFICATION forming part Of Letters Patent NO. 679,032, dated July 23, 1901. 4 Application filed November 26, 1900- Serial No. 37,788. (No model.)

To a. whom it may concern:

Be it known that I, JOHN H. OSBORNE, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have made a certain new and useful Invention in Thill-Oouplings; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of my invention as applied. Fig. 2 is a plan view of my antirattling attachment and the securing-bolt. Fig. 3 is a detail view of the bolt. Fig. 4 is a detail view of a modified form of bearing upon the bolt.

The invention has relation to thill-couplings; and it consists in the novelconstruction and combinations of parts constituting an antirattler and quick shift, all as hereinafter set forth.

In the accompanying drawings the letter A designates an axle, and B the clip, having the plate-bearing O and nuts (1. The clip B is provided with the usual projecting ears or lugs e, which are perforated for the passage of the securing-bolt.

F represents the securing-bolt, which is of J form, the long branch g being designed to pass through the perforations of the lugs e and of the eye kof the thill-iron L. The short branch h of the bolt is provided with a diskform bearing m, the periphery of which is made with a channel or spiral groove n, which is designed to engage one of the spirals or coils s of the antirattler spring Z. The grooved disk bearing m is made separately from the bolt, which is upset at its end to secure said bearing in position after the bolt and spring are connected. The opposite spiral or coil 3 of the spring is without a bearing. The spring Z consists of the middle portion or bend v, constituting the antirattler-tongue, the lateral spirals or coils S S, and the lateral rearward-extending loops t t, to which the attachment or locking-wire ais connected.

When the antirattler-tongue is placed in position against the eye of the thill-iron after the bolt has been passed through the perforations of the clip-lugs and eye, the rear extensions of the springs are brought up near the clip-plate and secured in this position by means of the transverse locking-wire or attachment-bail a, which is passed over the end of said clip-plate. When so placed, the antirattler-tongue is brought forcibly against the back of the eye of the thill-iron and serves to prevent any rattling movement of the same on the bolt, on which the elastic pressure of the spirals or coils is also exerted to hold it against the rear of the perforation of said eye. To shift the bolt in order to detach the thills, it is only necessary to cast 06 the trans verse locking-bail from the clip-plate. This allows the wire spring to fall to a low position, when the antirattler tongue can be withdrawn and the securing-bolt detached from the clip perforations and thill-eye.

It is designed by the means described to provide a very simple antirattler attachment which is effective and readily and easily shifted when necessary in detaching or attaching the thills.

It is apparent that instead of making the bend of the bolt in a rounded curve it may be made angular.- v

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. The J -form securing-bolt for thill-irons, having the channeled disk bearing secured to its short branch, substantially as specified.

2. The J-form securing-bolt for thill-irons, having a spirally-channeled disk bearing secured to its short end, substantially as specified.

3. The combination with the securing-bolt, having a short branch provided with a channeled disk, of a spring having an antirattlertongue, and a locking wire or bail, substantially as specified.

4. The quick-shift antirattler device consisting of the securing-bolt having a spirallychanneled disk on its short branch, the antirattler-spring having the middle tongue bend, the lateral coils and rear extensions, and the transverse wire bail or look, substantially as specified.

In testimony whereof I affixmy signature in presence of two witnesses.

JOHN H. OSBORNE.
